Lotus team principal Eric Boullier says "great things are possible" for Lotus this season after the team unveiled the E21.

The E21 is the first of the 2013 cars to be launched, with McLaren unveiling its new car on Thursday ahead of Ferrari on Friday and Red Bull on Monday. Lotus finished 2012 fourth in the constructors' championship behind those three teams and Boullier said the step it had made ahead of last year was cause for optimism heading in to the new season.

"I think it is fair to say that great things are possible," Boullier said. "The leap we made from 2011 to 2012 showed what we are capable of. Add to this the continuity and potential of our driver line-up and we have a very powerful cocktail for the season ahead. Our ambitious plan to turn ourselves into one of the top teams in Formula 1 is coming to fruition and now we need to harness this with strong and regular podium results."

Boullier said the formal target would be to improve on last season's results and win more races in 2013.

"We want to do better than we did last year. 2012 was a good season for us - certainly in the context of the previous season - but we, like every team in this highly competitive sport, want to win. We want to make regular appearances on the podium, and add to our tally of appearances on the top step."
